Constructor Detail

PnPassedFunction

public PnPassedFunction(PuFunction function)

Construct a new PnPassedFunction.

Parameters:

function - the function to evaluate, number of functions must be equal to 1.

Method Detail

getNumOfVariables

public int getNumOfVariables()

Get the number of variables.

Specified by:

getNumOfVariables in class PnFunction

eval

public double eval(PdVector x)

Evaluate the function at a specified position x.

Specified by:

eval in class PnFunction

evalGradient

public PdVector evalGradient(PdVector x,
                    PdVector aGradient)

Description copied from class: PnFunction
